The convergence circuit needs repaired. I did the same job yesterday on this model. I not only replaced the convergence ICs, but, I had to replace a couple of resistors and a coil. The convergence alignment was minor after that.

This kind of picture problem is due to failure of convergence out ICs, please replace convergence out ICs in tv to get it fixed.
If you are handy with electronics stuff repair and can replace parts in circuit board with proper tools then can replace above said ICs by yourself or ask local tv tech to repair your tv.

Double vision on tv with purple and green colors


This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

I have a JVC AV-56WP74 that all of the sudden has a bow screen on top and bottom with green and purple tint with double picture. I have tried to fix the problem working with the convergence troubble...

You need to replace both convergence ICs they are STK392-110 you may want to get the resistor kit as your model will usually have a couple open resistors. You can get replacement ICs and resistors at the following link and they provide free instructions with pictures so you can easially do the repair your self.
Heres the link.

You have a convergence problem. Components are shorted out and must be replaced. Unless you're a technician, there's really nothing you can do at this point.

Screen is bowed (top and bottom) Color has a green and purple tint?

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.
